Quant-UX

Quant-UX is a free, open‑source UX research hub that lets designers create interactive prototypes, share them via links or QR codes, and run usability tests with real users. It automatically records screen sessions, generates heatmaps, A/B test results, surveys and KPI analytics, and even offers design system support and an AI assistant to speed up workflow. Ideal for teams and educators seeking a low‑code, all‑in‑one solution for design validation and user research.
